The transmission path and the updating path set by the method automatically complete the pictures and the animations in three staged processes of style updating and system startup through the updating path after the style setting message acquired by the system is transmitted to the U-Boot layer.
The further scheme is that the transmission from top to bottom is divided into the following steps:
a. setting the style currently used as style 2, and switching the current style 2 into the state information of style 1 through a system and an Apk application layer to transmit downwards;
b. meanwhile, after the HAL & Framework layer is connected with the driving layer downwards, an interface is provided for JNI or HAL upwards, and the state information of the style 1 switched from the style 2 is transmitted downwards through the file system;
and c, the Kernel layer acquires the state information of switching the downward transmission style 2 into the style 1 through an IOCtrl driving interface, assigns a value through an RTC register, switches the transmission style 2 into the state information of the style 1, stores the state information and transmits the state information to the U-Boot layer.
The implementation of pictures and animations in three staged processes of bottom-to-top updating and system startup is divided into the following steps:
A. firstly, obtaining the assignment of an RTC register to obtain style information to be switched, obtaining the current style state by reading the style state information recorded in a Memory fixed area, and simultaneously unifying display interfaces to realize the loading of different styles;
B. the method comprises the steps of obtaining the style state of a U-Boot layer by reading specific data in a Memory area Nandflash, establishing a system file, updating the system state of the file at the same time for a HAL & Framework layer, a system and an Apk application layer, backfilling the style state, and displaying a logo through a display interface;
C. acquiring the style state updated by the Kernerl layer by reading the file system, backfilling the style state to update the file system after judging whether the style state is consistent with the current style animation state, and playing the animation through a playing interface;
D. the system and the Apk application layer acquire the updated style through the updated file system state, mark the updated style and complete the updating of the system style.
The RTC register set by the method can utilize the RTC spare Bit to store the transmitted style state information, and simultaneously set the transmitted style state information in the RTC register, so long as the system is not powered down or rewritten, the style state information in the RTC register is stored unchanged; and the JNI or HAL in the HAL & Framework layer has the function of starting and stopping, is communicated with the system and the application through a display interface, and is communicated with the Kernerl layer through a file system.
A further scheme is that the current style state is obtained in the step A, if the style state is not consistent with the style state in use, the current style state is loaded into a display interface, and the updated style state is recorded and stored in a Memory, and if the style state is consistent with the style state in use, the original qualified U-Boot Logo is loaded into the display interface for backfilling the state value; if the style state obtained in the step B and the style state obtained in the step C are not consistent with the style state in use, the style state in use is updated to the obtained style state, and the style state after switching is loaded into a file interface or a playing interface; and if the style state is consistent with the style state in use, loading the style state in use into a file interface or a playing interface. The setting of the method can compare the style state obtained by assigning the RTC register in the step A with the current style state, and if the style state is not consistent with the current style state, the obtained style state is stored in the Memory.
The method comprises the steps of dividing a Memory partition in a Memory hollow residual region, recording a switching state of styles, keeping a certain style state without being influenced by power failure, shutdown and factory restoration, presetting a plurality of styles in a system and Apk application layer, carrying out automatic customization and manual customization, wherein the customization process of the style of the system which is automatically customized is consistent with that of the system which is manually customized, and the styles preset in the system and the Apk application layer can be automatically customized by means of a She11 script. The method is arranged in a hollow residual region of the Memory, and the switching state of the exclusive Memory partition recording style is divided, so that the switching state of the style is kept most accurately, and meanwhile, the style of the system can be automatically switched through a Shell script arranged in the system.
The Android-based system style deep customization method provided by the invention has the advantages that the system style customization process mainly comprises style selection, the style selection mainly comprises a transmission path and an updating path, the transmission path displays different styles according to various conditions by pre-configuring styles of various different elements at various stages in a system and Apk application layer, and meanwhile, state information of switching styles is transmitted to a U-Boot layer; the updating path is that in the process of switching the two styles, the system automatically finishes the picture customization in the starting process from three different stages of a U-Boot layer, a Kernel layer, a HAL layer and a Framework layer, and the automatic customization of the system and the application style in the system and Apk application layers. The method greatly reduces the workload of software upgrading and the after-sale maintenance cost, and simultaneously meets the aesthetic requirements of customers on style diversification and customers of different age classes.
